Abstract
There is disclosed a method for forming a radiogram of an object comprising the steps of energizing an X-ray source at a low level of radiation intensity wherein the X-ray source includes a slit diaphragm, pivoting the X-ray source during a first scanning of the object, moving an elongated X-ray detector in respect to the pivoting of the X-ray source to generate an output signal of intensity of the object during the first scanning thereof, measuring the output signal during at least a portion of said first scanning, energizing the X-ray source to a higher level of radiation intensity as determined by the output signal from the X-ray detector during the first scanning, pivoting the X-ray source during a second scanning of the object, moving the X-ray detector during the second scanning to generate a second output of radiation intensity and forming a radiogram from the second output signals.
